| description | The decomposition of submerged organic matter after the flooding process of a reservoir and the organic matter transported by the tributaries that supply it, gives rise to the formation of greenhouse gases (GHG), such as CO2 and CH4, product of the aerobic and anaerobic biological processes that take place both on the surface and at the bottom of the reservoir. In this study, the dynamics of aerobic and anaerobic processes as well as the generation of greenhouse gases in the degradation of organic matter, present in a tropical reservoir, were compared. Batch reactors and plant material extracted from the protection strip were used. Likewise, the behavior of the variation of the COD, physicochemical parameters such as pH, dissolved oxygen, redox potential, and conductivity were evaluated, and the kinetic constants that represent the behavior of organic matter were defined. The results showed that the degradation of the organic material leads to the generation of GHG, however, when using water plus vegetal material, the GHG increased considerably after a time. This process is due to the fact that the plant material suffers the breakdown of its polymer chains and so it degrades more quickly, which increases the concentration of organic matter available to microorganisms. GHG values were on average 10.290 g CO2eq/m2.d with water only, and 24.536 g CO2eq/m2.d with water and vegetal material for aerobic processes. In anaerobic processes, the values were on average 12.056 g CO2eq/m2.d with water only, and 33.470 g CO2eq/m2.d with water plus vegetal material. These laboratory scale results allow analyzing the behavior of the reservoir and the incidence of flooded plant material on GHGs. |

La descomposición de la materia orgánica sumergida posterior al proceso de inundación de un embalse y la materia orgánica transportada por los tributarios que surten éste, da lugar a la formación de gases de efecto invernadero (GEI) como el CO2 y CH4, producto de los procesos biológicos aerobios y anaerobios que se llevan a cabo tanto en la superficie como en el fondo. En este estudio se comparó la dinámica de los procesos aerobios y anaerobios, y la generación de gases de efecto invernadero en la degradación de la materia orgánica presente en el agua de un embalse tropical, empleando reactores en batch y material vegetal extraído de la franja de protección de este. Asimismo, se evaluó el comportamiento de la variación de la DQO, parámetros fisicoquímicos como el pH, oxígeno disuelto, potencial redox y conductividad, y se definieron las constantes cinéticas que representan el comportamiento de la materia orgánica. Los resultados demostraron que la degradación del material orgánico da lugar a la generación de GEI, sin embargo, al emplear agua más material vegetal, los GEI aumentaron considerablemente después de un tiempo, proceso que se debe a que el material vegetal sufre el rompimiento de sus cadenas poliméricas y se puede degradar más rápidamente, lo que incrementa la concentración de materia orgánica disponible para los microrganismos. Los valores de GEI fueron en promedio de 10.290 g CO2eq/m2.d solo con agua y 24.536 g CO2eq/m2.d con agua y material vegetal para los procesos aerobios, mientras que en los procesos anaerobios fueron en promedio de 12.056 g CO2eq/m2.d solo con agua y 33.470 g CO2eq/m2.d con agua más material vegetal. Estos resultados a escala de laboratorio permiten analizar el comportamiento del embalse y la incidencia que tiene el material vegetal inundado sobre los GEI.
